Abstract: The material has collective surface diffusion thermodynamically into stable nano objects because of aging which may have the capability to enhance oxidative degradation performance. Here, Barium-tungstate nanostructures are synthesized using a hydrothermal method with an aging process, employing NaWO4·2H2O and Ba(NO3)2 as precursors and their photocatalytic performance have been measured. X-ray diffraction analysis confirmed the wolframite tetragonal structure. Morphological characterization via field emission scanning electron microscopy and energy-dispersive X-ray spectroscopy revealed dodecahedral shapes (average ~ 185 nm) for non-aged samples and spherical shapes (average ~ 60 nm) for aged samples. Optical properties, examined by UV-Vis and Fourier-transform infrared spectroscopy, showed an absorption peak at 262 nm and a characteristic band at 788 cm−1. Photocatalytic activity for degrading methyl orange dye under visible light was evaluated at varying pH values (2, 4, 6, 8, 10). At pH 10, degradation efficiencies were 96.96% for non-aged samples and 98.79% for aged samples, maximum activity results appeared with the aging process which enhancing performance by improving morphology and increasing active sites.
